    Re: mesa reseller ???

    The Issue with 5I25s (and 6I25s etc) is that the Xilinx Spartan 6 FPGA is not available
    (and may not be available for quite some time if ever)

    We have a replacement card coming out but it will...

    Nope 28 nm is heading for over supply.

    The center of supply line issues is actually closer to 100 nm

    Way to miss the point...

    The current chip shortage is chiefly in 45 nm and older processes

    ASML uses hundreds of US patents just for the EUV light source they acquired from Cymer (San Diego)
  7. Re: WOW ! Parts are getting a Wee bit hard to find now

    Certainly more diversity is a good thing, but the "eggs" dollar wise are mainly in high density chips which are not made in China.

    Re: PathPilot, Mesa 7I92H and Geckodrive G540

    Not sure why you think there is editing of pins required

    Stepgens and pwmgens are not addressed by pins and the GPIO pin numbers are the same for any configuration

    Re: PathPilot, Mesa 7I92H and Geckodrive G540

    Not really, if you use the correct bitfile (A bitfile for a G540) the pinout is correct and
    you have the proper resources for the G540: PWM and chargepump support

    Since this is not a Tormach...

    Re: Jerk Control in machines

    I think its valuable to divide jerk control into tangential jerk and centripetal jerk:

    Tangential jerk (along the tool path) is full controllable by the machine.

    Centripetal jerk is totally...

    Re: PathPilot, Mesa 7I92H and Geckodrive G540

    Pretty sure Tormach uses the 10.10.10.10 IP address so IP jumpers need to be
    W5 DOWN, W6 UP

    But beware, Path pilot will write it's bitfile to the 7I92, which is not what you want for a G540...

    receiver or buffer for the encoder signals rather than use...

    Re: 7i76E; How to properly turn on?

    As long as you switch the AC side you should be fine.

  17. Re: Tormach pcnc 1100 running off spruce software

    Using a 7I92H would give you a PathPilot supported, Ethernet connected device that will connect directly to the Tormachs
    breakout with a short 26 pin flat cable.

    Re: Conversion to LINUX CNC EMCO pc mill 50

    The difference between the 7I76E and 7I76ED is the outputs _not_ the inputs
    The 7I76E has sourcing outputs (PNP type)
    The 7I76ED has sinking outputs (NPN type)

    The inputs on both are sinking so...

    The Gecko drive could not change an arc to a circle, that's more likely a controller or Gcode fault

    Re: Renew old plasma table

    Have you considered using LinuxCNC+PlasmaC?

    This would allow re-using your existing drives and having full feedback to the controller
    (which you lose if you go to a step/dir system)
